1. Product Description

Graphite electrode is the use of petroleum coke as aggregate, coal tar pitch asbinder, a high temperature and oxidation resistance of conductive material through crushing, proportioning, mixing kneading, shaping, roasting, soaking, graphite,mechanical processing and a series of production process.

Graphite electrode has good electrical properties and chemical stability, mechanical strength at high temperature under high, low impurity content, good anti vibration performance. Is a good conductor of heat and electricity. Widely used in electric arc furnace steelmaking, refining furnace, the production of iron alloy, industrial silicon,phosphorus, corundum and so on ore smelting furnace and other use of arcproducing high-temperature smelting furnace.

According to the different power and current when in use, the production using different raw materials and production technology, can be divided into regular power graphite electrode, high power graphite electrode, ultra high power graphiteelectrode. According to the diameter of the electrode with diameter of 75~600mmdifferent, different specifications. According to the special requirements of users, butthe special specification production of graphite electrode and special shaped graphite products.
